The DELL Latitude 14 E7450 has a better storage medium than most portable PCs of this age and type. This laptop has an SSD storage medium, whereas most medium processor core laptops that have been around for a similar time to it have an HDD storage medium. Solid State Drives (SSD) store data in semiconductors on a circuit board rather than using magnetic or optical media. Solid State Drives have no moving parts which makes them very fast and reliable.
This portable PC's storage medium (SSD) is in fact the best storage medium across all laptops that have been on the market for more than a year.
Across similar types of portable PC the worst storage medium is HDD.
We compared this laptop to all the other notebook PCs that have an SSD storage media and we think a cheaper portable PC such as the Z30, and the Z30 both from Toshiba or the DELL Latitude 12 7000 or you might consider a higher scoring portable PC such as the Satellite Z30, and the Satellite Z30 both from Toshiba are also worth considering.
